Obesity is a rapidly growing health problem worldwide and its prevalence has increased markedly in both the developing and developed nations. It is associated with a range of co-morbidities such as cardiovascular disease, type 2 diabetes mellitus, and cognitive dysfunctions. Therefore, the need for a safe and effective treatment has led to the exploration of natural products for the management of obesity. In the present study, we tested the anxiolytic, anti-apoptotic, and anti-neuroinflammatory potential of Tinospora cordifolia in a high fat diet-induced obesity rat model system. Young female Wistar albino rats were divided into three groups: (1) Low fat diet (LFD), fed on normal chow feed; (2) High fat diet (HFD), fed on diet containing 30% fat by weight; and (3) High fat diet containing extract (HFDE), fed on high fat diet supplemented with the stem powder of T. cordifolia (TCP). The rats from each group were kept on their respective feeding regimen for 12 weeks. The body weight and calorie intake were recorded weekly. The elevated plus maze test and rotarod performance test were performed to evaluate the anxiety-like behavior and locomotor coordination, respectively. The levels of serum cytokines (IL-6 and TNF-α) were estimated and various markers for inflammation, synaptic plasticity, apoptosis, and energy homeostasis were studied by western blotting. The HFDE rats showed reduced anxiety-like behavior and improved locomotor behavior as compared to HFD-induced obese rats. The TCP supplementation in highfat diet suppressed the expression of inflammatory molecules, including serum cytokines (IL-6 and TNF-α), and modulated apoptosis and synaptic plasticity. TCP was found to be effective in managing body weight in HFD-fed rats by maintaining energy metabolism and cellular homeostasis. T. cordifolia may be recommended as a potential therapeutic agent to prevent the adverse effects of obesity and obesity-associated brain dysfunctions.
